Application lediFebruary 15, A1912. Serial No. 677,818.

Shoe Heel, of which the following is a" specifica-tion.

,tachably position 'and oneobject of the or shoe heels which involve a block of relativelyyielding material which 1s h'eld de- 'i inventionf is to provide a construction in 1 which thel detachable rubber heels can be removed in a very-simple manner and inter-chalnged, vthe right with the left, so that .the durability will be substantially doubled, .or replaced by new ones.

The invention also involves the use of a locking device to hold the heelinposition which, when in operation, is located entirely within the walls of the heel and involves no ments.

Reference is to bel had to the accompanying drawings in which- Figure 1 is a side elevation of a portion of a shoe with a preferred form of this-iii vention applied thereto. Fig. 2 is a bottom plan view of the same with parts broken .away to show interior construction and illus-- trating a portion of the rubber heel in section.. Fig. 3 is a view of the front of the heel with the parts locked in position. Fig. 4 is a similar view ofl the detachable rubber portion of the heel, and Fig. 5 is a plan of the locking and holding device shown extended'.

The invention is shown as applied to a leather heel plate constituting the top of the heel in the case illustrated, but of course it will be understood that this plate may be surmounted by any desired number of lifts l forming thedesired'height of heel. Secured metallic casing 12 of the shape of the heel on 'the outsideand hollow so asito provide a space for part of the detachable rubber heel. These-nails pass through lugs 12a integral with the casing, which is provided with4 al slot 13paral1el`with its top and bottom l faces-and-extending past vthese several lu This invention relates to that class of boot all Thev slot 13 is substantially the same wi all around the heel except at a point 14 on oted -as will appear hereinafter.

Onf the rear ofthe heel is a pivot 16 on which 'two vside frame members 17 and 18 are pivoted. lEach vof these is designed to swing into the slot 13 on its side and when innal position, to be flush with the outside j of the 4heel and of the casing. Each one is provided vwith a pluralit of pins 19, each substantially tangent to t e circle on which it swings about the pivot 1650 that they frame piece swings inwardly. Both frame pieces extend to the front of the heel. A short. strip 20 is pivoted to the front end of the arm 18. IIt' has .projections or pins 19 arranged similar to those previously described. This is also designed to come Hush it is provided with a notch 21 and with an integral projection 22'which forms a latch to fit into a notch 23 in the end of the side arm 17, as shown more particularly in Fig. 2, to lock these parts in position. When in this position, the latch is swung into closedposition, as shown in Figs. 2 and 3, .to hold them all in place. It will be understood, of course, that thepins 19 are discontinued Where they would come opposite the rivets 11 and the other pins extend clear through the slots 13. This frame is designed to hold a detachable rubber part or block 25 having a. bottom portion of the same outside size as the heel and an inner projection 26 of reduced size, just fitting the inside of. the -rame 12. It is' provided with notches 27 registering with the lugs 12a of the frame provided for the nails 11 and also is pro- -vided with permanent horizontal sockets or recesses 28 in its vertical edges for receiving thepins 19. In order to reduce the liability of the displacementof the rubber to this plate by-nails 11 or the like isl a fixed i "the front where a locking latch 15 is pivwill come into the heel longitudinally as the with'the front edge vof the heel. v At its end A rounded off .at th'e front, as shown at 29.

'On .account of this, when the heel strikes an obstacle part of the force of. the blow is expended in lifting the foot. y

In operation, the rubber heel is set into the frame when it is extended, as shown in Fig. -5, then the side member or arm 17 is closed up and afterward the members or arms 18 and 20 'to bring the parts into the posi- -tion shown in Figs. l, 2 and 3.

It is a very simple and convenient thing .todismount this heel, by swinging out the side members, to interchange the eels, the right for the left, so as to compensatefor the wear, or to insert a new one. At the same time it is obvious that the device is light, presents no -projections beyond the outline 'of the heel, and does not require the provision of any. metallic members on the rubber heel itself.

Although I have illustrated and described a preferred embodimentofv the invention and shown the details thereof, I am aware that many modifications can be made therein by any person skilled in theart'without departing from the scope of` the invention as .expressed in the claims. Therefore, I donot -wish to be limited to all the details of construction herein Shown'and described, but

What I do claim is 1. As an article of manufacture, a boot or shoe heel comprisinga rubber part having horizontal sockets along its vertical edges and a movable frame provided with a series of pins for entering said sockets to* hold the rubber part in position.

2. As an article of manufacture, a heel having al hollow casing, amovable member,

a rubber'portion having a reduced projec- -tion at the top entering said casing and' provided with horizontal sockets inthe edgesh of said reduced projection, and horizontally movable pins carried by said\ movable member for entering said .sockets and holding the rubber portion in place.

3. As an article of manufacture, a heell having at the bottom thereof a lxed metallic casing provided with side `(passages therethrough, and' a pair of pivote arms ada ted to swing into said assages 's'oas to be ushl with their outer si es andv having inwardly extending projections for holding a removable attachment.

4. As an article of hmanufacpre, a heel of the 'heelA and provided with a horizontal.

slot surrounding the heel, and movable.

members located in said slot 'and' forming a continuation of the outer surface of the heel on'their outer sides, and provided with inwardly extending means. for'- detachably' holding a rubber attachment at the bottom of the heel.-

liush with said casing, and having inwardly.

extending projections for holding a removable attachment, both -of said members eX- tending substantially to` the front of the heel, one of them terminating therehand the other having a pivotedarm on the front end .thereof adapted to lie flush with the front side of the h'eel, and .provided with a projection adapted to extend over a portion of the opposite side member to lock it in position. I

8. As an article of manufacture, a heel for a boot or shoe having at the bottom thereof, a pair of members pivoted to swing inwardly and having inwardly extending projections for holding a removable attachment, one of said members having a pivoted arm on the front end thereof, prgvided with a projection adapted to extendver a portion of the'opposite side member to lock it in position and an additional lock for said front mem er mounted on the heel.

9. As an article 'of manufacture, a heel for a boot or shoe having a pair of side members pivoted to swing and having inwardly extending projections for holding a removable attachment, said projections comprising metallic pins fixed in said side members and movable in arcs about the'pivots of the side members as the side members swing into position.
